The upper sash movements are controlled in a similar Ina-nner bypressing heads 38 and 39 and their stems inwardlykagainst the action ofsprings 40 and 41, so that hook 34 is disengaged from rack teeth 20, andthe sash may now be lowered to any desired extent, and be held in any ofits ladjusted positions by re-enfa rrement of hook 34 with the rackteeth 20 under the action of springs 40, 41, after release of thepressure on heads38, 39. j

It will be understood that have described and shown some of the possiblepractical con- ,structions of my metal window frame and that I may makechanges therein such as are ,warranted by the appended claim withoutdeparture from my invention.

Having thus described my invention what I claim as new, and desire toseeureby Letters Patent is:

In a metal window, sash guides and sashes guided therein, rack teethformed on part of said guides, chambers formed in the sashes,

an angular bracketin one of said chambers, the chamber for the lowersash, the horizontal arm' of said bracket attached to the bottom ofsaidchamber the end of the vertical arm vof said bracket formed into a hookengaging between the teeth of said guides, and a curvedvleaf springattached at one end to the inner wall of said chamber oppositelydisposed to said hook, its-lower free .end bearing against the hook armof said bracket for pressing the same into engagement with said rackteeth, and a headed stud' extending Vfrom `said hook to the outside forallowing a repressing of the saine into the-chamber to disengage itfrom'the rack teeth,a front plate Y 'for the other yof said chambers inthe upper sash having an opening therein, aplate bearing kagainstA saidfrontfplate', a hook'formed withsaid'plate extending through the openingof said front plate into engagement with the rack teeth,stu'ds'extending from the ends of said hook plate towards Atheoutside'and carrying headspand springs wound at -one end about the innerends of said' studs, and pins projecting into said chamber about whichtheother ends of Vsaid springs are wound'to normally press said' hookinto engagement with said rack.
